iMPROVEMENT IN DEVICES FOR PREVENTING THE UNROLLING 0F TAPE. &c., FROMSPOOLS.

Specification forming part of Letters Patent No. 191,581, dated June 5,1877; application filed April 9, 11377.

To all whom it may concern:

Be it known that I, ARTHUR. G. GOULD, of Brookliue, in the county ofNorfolk and State of Massachusetts, have invented a Device forPreventing the Unrolling of Tape, 8110., from Spools, of which thefollowing is a specification:

The object of my invention is to produce a device to be used inconnection with a spool of tape, braid, or ribbon, for the purpose ofpreventing the tape, &c., from running off the spool when in ordinaryuse, or when a piece of the same has been out off.

The invention consists of a piece of wire having its ends bent at rightangles, and inserted in opposite sides of a spool on whichis wound tape,braid, or ribbon, and extending up over the outer surface of the tape,850., the wire being doubled on thepart that passes over the outersurface of the coil, so that in passing the tape, 860., through theupper portion of the wire loop, and returning it under the doubledportion, the tape will be held in place on the spool, and prevented fromunrolling or becoming loosened on the spool.

The usual method of retaining the tape, &c., in place on the spool aftercutting off a piece is to put a pin in the tape at its end, and if thepin happens to come out, the roll of tape will become loosened andrequire to be rewound.

Referring to the drawings, Figure l is a perspective view of myinvention. Fig. 2 is a section of a spool of tape or braid with myinvention applied.

A is an ordinary spool, upon which is wound a piece of tape, braid, orribbon, B. O is a piece of wire, bent in the form shown in Fig. 1. Theends d d are bent at right angles to the sides 0, and are inserted, oneend in each side of the center of the spool A. The wire extends over theoutside of the braid or tape, and upon the top is bent over twice, so asto form a loop, as shown in Fig. 1. The end b of the tape is passedunder the lower piece a ot the loop, and then returned over the samebetween the folds of the loop, so as to be held sufficiently tight toprevent it from unrolling of its own accord, and yet to be easily drawnthrough the same.

It will thus be seen that, however much of the tape or braid may beunwound from the spool, the remainder will be held in place andprevented from unwinding.

One of the arms or side pieces of the frame 0 may be dispensed with, andthe part d of the opposite or remaining arm be passed through the centerof the spool, it desirable,

What I claim as my invention is- A tape or braid guard consisting of asingle piece of wire, 0, with the bent ends d d and the double loop a,as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

A. O. GOULD.
